4. MOUNTING

• Choosing a Location to Mount the Inverter

Be sure the inverter is protected from the following conditions:

• Extreme cold and heat. Use only within the ambient temperature range (for open

chassis type): 14 to 122°F (-10 to +50°C)

• Rain, moisture.

• Oil sprays, splashes.

• Salt spray.

• Direct sunlight. (Avoid using outdoors).

• Corrosive gases (e.g. sulfurized gas) or liquids.

• Dust or metallic particles in the air.

• Physical shock, vibration.

• Magnetic noise. (Example: welding machines, power devices, etc.)

• High humidity.

• Radioactive substances.

• Combustibles: thinner, solvents, etc.

Page 36

• Mounting Dimensions

Clearances as shown below are required when mounting the VS mini.

Page 37

• Mounting/Removing Components

Removing and Mounting Digital Operator and Covers

• Removing front cover

Use a screwdriver to loosen the screw on the front cover surface to direction 1 to remove it. Then press the right and left sides to direction 2 and lift the front cover to direction 3.

• Mounting front cover

Insert the tab of the upper part of the front cover into the groove of the inverter. Press the lower part of front cover onto the plastic case until the cover snaps shut. Tighten the screws.

• Removing option cover

After removing front cover, remove the option cover to direction 2 with section A as a supporting point.

• Mounting option cover

Mount the terminal cover in the reverse order of the above removal procedure.

• Removing upper/bottom covers

After removing front cover, lift the top and bottom covers to direction 1.

• Mounting upper/bottom covers

Mount the front cover in the reverse order of the above removal procedure.

5. WIRING

• Wiring Instructions

(1) Always connect the power supply via a molded-case circuit breaker (MCCB) to the

power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase). Never connect the power supply to U/T1, V/T2, W/T3,-,+1 or +2.

The single-phase (200V class) inverter can be connected to a 200V 3-phase input.

However, when a single-phase supply is used, never use the terminal T/L3 for other purposes.

200V Single Input Power Supply Specification Product. CIMR-J7!!B!!!

400V 3-phase Input Power Supply Specification Product. CIMR-J7!!4!!!

(2) Connect the motor wiring to terminals U, V, and W on the main circuit output side

(bottom of the inverter).

(3) If the wiring distance between inverter and motor is long, reduce the inverter

carrier frequency. For details, refer to “Reducing motor noise or leakage current (n46)” on page 79.

(4) Control wiring must be less than 164ft(50m) in length and separate from the power

wiring. Use twisted-pair shielded wire when inputting the frequency signal externally.

(5) Tighten the screws on the main circuit and control circuit terminals.

(6) Do not connect or disconnect wiring, or perform signal checks while the power

supply is turned ON.

• Typical setting of V/f pattern Set the V/f pattern according to the application as described below. For 400V class, the voltage values (n10, n13, and n15) should be doubled. When running at a frequency exceeding 50Hz/60Hz, change the maximum output frequency (n09).

Note: Be sure to set the maximum output frequency according to the motor

characteristics.

Increasing voltage of V/f pattern increases motor torque, but excessive increase may cause motor over excitation, motor overheat, or vibration.

Page 60

When operating with frequency larger than 60Hz/50Hz, change only maximum output frequency (n09).

• Full-range automatic torque boost

Motor torque requirement changes according to load conditions. Full range automatic torque boost adjusts voltage of V/f pattern according to the requirement. The VS mini J7 automatically adjusts the voltage during constant-speed operation as well as during acceleration. The required torque is calculated by the inverter. This ensures tripless operation and energy-saving effects.

Output voltage Torque compensation gain (n63) Required torque

∝

Operation

Normally, no adjustment is necessary for torque compensation gain (n63 factory setting: 1.0). When wiring distance between the inverter and motor is long or when motor generates vibration, change the automatic torque compensation gain. In these cases, it may also be beneficial to adjust the V/f pattern (n09 to n15).

Page 62

• Selecting Run/Stop Commands

Refer to page 63 to select either the LOCAL mode or REMOTE mode. Operation method (RUN / STOP commands, FWD / REV run commands) can be selected by the following method.

• LOCAL Mode

When Lo (local mode) is displayed on the digital operator (when is illuminated), or when the LOCAL / REMOTE changeover function is set as a

multi-function input and the input terminal is turned ON, run operation is enabled

by the or of the digital operator. FWD/REV is selected by

illuminating and using or key to select FWD or REV.

• REMOTE mode

• Select remote mode The following two methods are used to select remote mode:

1. Select rE (remote mode) for selection.

2. When the local / remote switching function is selected as multi-function input selection, turn OFF the input terminal to select remote mode.

• Select operation method by setting the parameter n02. n02=0: Enables the digital operator (same with local mode) =1: Enables the multi-function input terminal (see fig. below) =2: Enables communications (refer to page 96)

• Example for using the multi-function input terminal as operation reference (two-wire sequence) follows. For 3-wire sequencing, refer to page 85.

• Operating (RUN /STOP commands) by communications (When option card is installed)

Setting parameter n02 to 2 in REMOTE mode can give RUN / STOP commands by communication (MEMOBUS). For details, refer to page 96.

Page 63

• Selecting Frequency Reference

Frequency reference can be selected by the following methods.

• Setting by operator

Select REMOTE or LOCAL mode in advance. For the method of selecting the mode, refer to page 62.

LOCAL mode

Parameter n07 determines where the frequency reference is input from when in the local mode. n07 =0: Enables the setting by volume on digital operator (initial setting)

Factory setting of the model with operator (without volume) is n07=1.

=1: Enables the digital setting by digital operator, setting value is stored

in parameter n21 (frequency reference 1).

• Digital setting by digital operator

Input frequency while FREF is illuminated (press ENTER after setting the desired frequency value).

Frequency reference setting is immediately effective when n08 = 1 The ENTER key does not have to be pressed to enter the reference. n08 =0: Enables frequency reference acceptance by ENTER key.

=1: Disable frequency reference setting by ENTER key. It is not necessary

to press the ENTER key to accept the reference.

REMOTE mode

Parameter n03 determines where the frequency reference is accepted from when in the REMOTE mode. n03 =0: Enables frequency reference setting by volume on digital operator.

=1: Frequency reference 1 (parameter n21) is effective =2: Voltage reference terminal “FR” is effective (0 to 10V)

(See the figure below)

=3: Current reference terminal “FR” is effective(4 to 20mA)

(Refer to page 90)*

=4: Current reference terminal “FR” is effective (0 to 20mA)

(Refer to page 90)*

=6: Communication (Refer to page 97)

Page 64

*NOTE: SWB must be set to the “I” position when using terminal “FR” as a

current reference input.

Example of frequency reference by voltage signal

n03: 2 (factory setting)

SW8 is set to “V” position when using terminal “FR” as a voltage reference (default setting)

Page 65

• Setting Operation Conditions

Reverse run prohibit (n06)

The “Reverse run disabled” setting will not accept a reverse run command from the control circuit terminal or digital operator. This setting is used for applications where a reverse run command is undesirable.

Setting Description

0 Reverse run enabled 1 Reverse run disabled

Multi-step speed selection

Up to 8 preset references can be selected by using Multi-Function inputs.

Example: 8-step speed reference

n02=1 (operation mode selection) n03=1 (Frequency reference selection) n21=25.0Hz (Frequency reference 1) n22=30.0Hz (Frequency reference 2) n23=35.0Hz (Frequency reference 3) n24=40.0Hz (Frequency reference 4) n25=45.0Hz (Frequency reference 5) n26=50.0Hz (Frequency reference 6) n27=55.0Hz (Frequency reference 7) n28=60.0Hz (Frequency reference 8)

When all multi-function reference inputs are OFF, frequency reference selected by parameter n03 (frequency reference selection)

becomes effective.

Operating at Jog frequency reference

By inputting a jog command and then a forward or (reverse) run command, operation is enabled at the jog frequency set in n29. When multi-step speed references 1, 2, 3 or 4 are input simultaneously with the jog command, the jog command has priority.

Name parameter No. Setting Jog frequency reference n29 Factory setting: 6.00Hz Jog command n36 to n39 Set to “10” for any parameter.

Page 67

• Adjusting speed setting signal

The relationship between the analog input signal and internal (terminal “FR”) frequency reference can be set by parameters n41 and n42.

FREQUENCY REFERENCE

(a) Frequency reference gain (n41)

The analog input voltage level for the maximum output frequency (n09) can be set in units of 1%. (maximum output frequency n09=100%)

∗ Factory setting : 100%

(b) Frequency reference bias (n42)

The frequency reference provided when the analog input is 0V (4mA or 0mA) can be set in units of 1%. (Maximum output frequency n09=100%)

∗ Factory setting : 0%

Example settings:

• To operate the inverter with frequency reference of 0% to 100% at 0 to 5V input

Gain n41 = 200% Bias n42 = 0%

Page 68

• To operate the inverter with frequency reference of 50% to 100% at 0 to 10V input

Gain n41 = 100% Bias n42 = 50%

Page 69

Adjusting frequency upper and lower limits

Frequency reference upper (n30) and lower (n31) limits determines the range over which the inverter will operate.

• Frequency reference upper limit (n30) Sets the upper limit of the frequency reference in units of 1%. (n09: Maximum output frequency = 100%) Factory setting: 100%

• Frequency reference lower limit (n31) Sets the lower limit of the frequency reference in units of 1%. (n09: Maximum output frequency = 100%) When operating at frequency reference 0, operation is continued at the frequency reference lower limit. However, when frequency reference lower limit is set to less than the minimum output frequency (n14), operation is not performed. Factory setting: 0%

Using two accel/decel times

* When “deceleration to a stop” is selected (n04 = 0)

Two acceleration times and two deceleration times can be selected via a multi-function input. Programming any of terminals S2 through S5 (parameter n36 to n39) to “11” “Accel/Decel time select”, provides the ability to switch between the 2 acceleration times (n16 and n18) and deceleration (n17 and n19) through a contact closure applied to the appropriate terminal (See timing diagram above).

Page 70

At OFF: n16 (accel time 1) are used.

n17 (decel time 1)

At ON: n18 (accel time 2) are used.

n19 (decel time 2)

• Accel time Set the time needed for output frequency to reach 100% from 0%.

• Decel time Set the time needed for output frequency to reach 0% from 100%.

(Maximum output frequency n09 = 100%)

Automatic restart after momentary power

loss (n47)

The inverter has the ability to ride thru momentary power outages provided the control logic power supplies are maintained.

When momentary power loss occurs, operation restarts automatically.

Setting. Description

0 Continuous operation after momentary power loss not provided.

2*†

The following time chart shows FWD/REV run switching at deceleration to a stop.

Overtorque detection

If an excessive load is applied to the machine, output current increase can be detected to output alarm signals to multi-function output terminals MA and MB.

To output an overtorque detection signal, set output terminal function selection n40 to “overtorque detection” [Setting:6 (NO contact) or 7 (NC contact)].

∗ Overtorque detection release width (hysterisis) is set at approx. 5% of inverter rated current.

Detected during running, operation stops during detection. (fault).

(1) To detect overtorque at accel/decel, set to 3 or 4.

(2) To continue the operation after overtorque detection, set to 1 or 3.

During detection, the operator displays “ ” alarm (blinking).

(3) To halt inverter by a fault at overtorque detection, set to 2 or 4. At detection, the

operator displays “ ” fault (ON).

• Overtorque detection level (n60)

Sets the overtorque detection current level in units of 1%. (Inverter rated current = 100%) Factory setting: 160%

• Overtorque detection time (n61)

If the time when the motor current exceeds the overtorque detection level (n61), the overtorque detection function operates. Factory setting: 0.1sec.

Frequency detection (n58)

Effective when the multi-function output terminal MA-MB-MC (parameter n40) is set to “frequency detection” (setting: 4 or 5). “Frequency detection” turns ON when output frequency is higher or lower than the frequency detection level (n58).

• Frequency detection 1 (Output frequency > (Set n40 to “4”.)

• Frequency detection2 (Output frequency < (Set n40 to “5”.)

Frequency detection level n58)

Jump frequencies (n49 to n51)

This function allows the prohibit or “jumping” of critical frequencies so that the motor can operate without resonance caused by machine characteristics. This function is also used for dead band control. Setting the value to 0.00Hz disables this function.

Set prohibited frequency 1, 2 or as follows:

n49 > n50 If this condition is not satisfied the

inverter displays for one second and restores the data to original

settings.

Continuous operation is prohibited within the jump frequency range.

However, during accel/decel the output frequency ramps through the jump frequency range (without jumping).

Continuing operation by automatic

fault reset (n48)

Sets the inverter to restart and reset fault detection after a fault occurs.

The number of self-diagnosis and retry attempts can be set with n48 (0 thru 10 restarts).

The inverter will automatically restart after the following faults occur:

• OC (overcurrent)

• GF (ground fault)

• OV (over voltage)

The number of retry attempts are cleared to 0 during the following cases:

(1) If no other fault occurs within 10 minutes after retry

(2) When the fault reset signal is ON after the fault is detected

(3) Input power is turned OFF

Page 76

Starting into a rotating motor - Tripless Operation

To start into a coasting motor without trip, use the speed search command or DC injection braking at start.

• Speed search command

Speed matches into a coasting motor upon starting without stopping the motor. This function enables smooth switching between motor commercial power supply operation and inverter operation.

Set input terminal function selection (n36 to n39) to “14” (search command from maximum output frequency) or “15” (search command from set frequency).

Build a sequence so that FWD (REV) run command is input at the same time as the search command or after the search command. If the run command is input before the search command, the search command becomes disabled.

• Time chart at search command input

• DC injection braking at start (n52, n54)

When starting into a coasting motor, use DC injection to gradually brake the motor before beginning the acceleration ramp. Set the DC injection braking time at start in n54 in units of 0.1 second. Set DC injection braking current in n52 in units of 1% (inverter rated current = 100%). When the setting of n54 is “0”, DC injection braking is not performed and acceleration starts from the minimum output frequency.

When n52 is set to 0, acceleration starts from the minimum output frequency after base blocking for n54 setting time.

Page 77

Accel/Decel Hold

To hold acceleration or deceleration, use a multi-function input that is set to a value of “16: Accel/Decel Hold. The output frequency is kept constant when the accel/decel hold command is input during acceleration or deceleration.

When the run command is removed during an accel/decel hold condition, accel/decel hold is internally released and operation ramps to stop.

Set multi-function input terminal selection (n36 to n39) to 16 (accel/decel hold command).

Note: When the FWD (REV) run command is input along with the accel/decel hold com-

mand, the motor does not operate. However, when frequency reference lower limit (n31) is set greater than or equal to minimum output frequency (n14), the motor operates at frequency reference lower limit (n31).

Operator stop key selection (n06)

Selects whether the “STOP” key on the digital operator is effective when operating the inverter by an external source (input terminals or serial communications).

Setting Description

STOP key effective when running either from multi-function input terminals or communications. When STOP key is pressed, the inverter stops according to the setting of parameter n04. At this

time, the digital operator displays “ ” alarm (blinking). This stop command is held in the

inverter until both forward and reverse run commands are open, or until run command from communications becomes zero.

STOP key is ineffective when running either from multi-function input terminals or communications.

• Selecting Stopping Method

Selecting stopping method (n04)

Selects the stopping method when the run command is removed.

Setting Description

0 Deceleration to stop 1 Coast to stop

• Deceleration to stop (n04 =0)

* When frequency reference is changed during running.

Upon removal of the FWD (REV) run command, the motor decelerates at the decel rate determined by the time set to decel time 1 (n17) and DC injection braking is applied immediately before stop. DC injection braking is also applied when the motor decelerates by setting the frequency reference lower than minimum output frequency while the(n14) with FWD (REV) run command remains ON.

If the decel time is short or the load inertia is large, an over voltage (OV) fault may occur during deceleration. In this case, increase the decel time.

Page 83

• Coast to stop (n04=1)

* When frequency reference is changed during running.

Upon removal of the FWD (REV) run command, the motor starts coasting.

Applying DC injection braking

• DC injection braking current (n52) Sets DC injection braking current level in units of 1%. (Inverter rated current=100%)

• DC injection braking time at stop (n53) Sets the DC injection braking time at stopping in units of 0.1 second. When the setting of n53 is 0, DC injection braking is not performed but inverter output is shut OFF at the timing of DC injection braking start.

When coast to a stop is selected as the stopping method selection (n04), DC injection braking at stop does not operate.

• Preventing Motor from Stalling (Current Limit)

This function automatically limits the output current in response to load changes by adjusting the output frequency to prevent motor stalling.

• Stall prevention (current limit) level during acceleration (n56) Sets the stall prevention (current limit) level during acceleration in units of 1% (Inverter rated current = 100%).

Factory setting: 170%

A setting of 200% disables the stall prevention (current limit) during acceleration. During acceleration, if the output current exceeds the value set for n56, acceleration stops and frequency is maintained. When the output current goes down to the value set for n56, acceleration continues.

* Stops the acceleration to prevent the motor

from stalling.

† Release width (hysteresis) of stall prevention

during accel is approx. 5% of inverter rated current.

In the constant horsepower area [output frequency > max. voltage output frequency (n11)], following equation automatically decreases the stall prevention (current limit) level during acceleration.

*Note: The lower limit of the stall prevention level is 40% of the level set in n56.

Page 92

• Stall prevention (current limit) level during running (n57)

Sets the stall prevention (current limit) level during running in units of 1% (Inverter current = 100%).

Factory setting: 160%

A setting of 200% disables the stall prevention (current limit) during running.

If the output current during speed agree exceeds the value set for n57 for longer than 100msec, deceleration starts.

As long as the output current exceeds the value set for n57 deceleration continues. When the output current goes below the value set for n57, acceleration begins to the set frequency.

The accel/decel rates during stall prevention are determined by the accel time (n16 or n18) and decel time (n17 or n19) that is selected at the time of the stall prevention condition.

* Decreases frequency to prevent the motor

from stalling.

† At acceleration start, output hysteresis is

The electronic thermal overload function calculates motor temperature, based on inverter output current and time, to protect the motor from overheating. When the electronic thermal overload relay is enabled and excessive current is flowing to the motor, an “ ” error occurs, shutting OFF the inverter output and preventing

excessive overheating in the motor. When operating with one inverter connected to one motor, an external thermal relay is not needed. When operating several motors with one inverter, install a thermal relay on each motor and disable the electronic overload protection (n33=2).
